The anti-aliased outline color was incorrectly blended
at the multiply option.
The fix can be observed in the example:
'examples/lottie/resourcesguitar.json'
in order to do this, RenderMehthod::blend() method introduced
`bool direct` for figuring out the intermediate composition.
An uint8_t version of the lerp function
is introduced to handle cases where
the interpolation factor t exceeds 1, which
previously caused overflow issues due to casting.
The range of saturation and brightness values is 0 ~ 100% and range of hue is 0 ~ 360.
If a value greater than 100% is loaded, it will be modified to be 100%.

To avoid editing the trim path values provided
by the user, the logic for their interpretation
was moved from the API to the renderer (7c87d8e).
This caused an issue in the lottie animations when
the trim path is applied more than once. Now fixed.

previously font size & italic style had been ignored
even if its attributes are changed.

Due to the lack of an analytical solution for Bezier
curves offsetting, a simple and computationally cheap
approximation has been implemented. The algorithm shifts
the segments connecting control points and determines
new points based on their intersections.

The occurrence of a 'carriage return' (13) or 'end of text' (3)
caused the skipping of the next character check, immediately
searching for it in the list of available characters.
If the next character was also 13 or 3, it led to incorrect
interpretation; however, if it was the last character in the
sequence, a crash occurred.
The y range initialization was missing a check to ensure
that the height is a positive value. This could lead to
an attempt to call malloc with a negative argument, which
cast to an unsigned value, caused a crash.
Spec out this incomplete experimental feature,
this is a still promising one, we will reintroduce
this officially after 1.0 release

A pkgconfig file is already provided, which enables using `thorvg` once
it is installed. However, this file is not, and cannot be, available at
setup time if using `thorvg` as a subproject.
In such cases, Meson provides the `override_dependency` mechanism for a
subproject to tell its parent how to use it.
In certain cases, the user might want to set mapped memory directly.
This update ensures that a null terminator is appended to the string data.

For rounded rectangles the roundness value should
be determined using to the formula:
r = min(r, max(size.x, size.y)/2)
rather than the previous method:
r = min(size.x/2, size.y/2, r)
The epsilon value currently used for the precision
of Beziers calculations is sufficient for comparing
curve lengths. However, for the parameter t, which
ranges from 0 to 1, an accuracy of 1% can introduce
errors.
The solution is to increase the precision for the t
parameter while keeping the rest of the calculations
at the previously used epsilon value.

In case of modern systems, size is not a big problem,
so we turn the optimization option to default
for better performance.
FPS: ~20% enhanced
Size: ~25% increased
Note that this doesn't affect to the web player.
The current Paint::bounds(transform=true) returns the coordinates
of the paint in its local coordinates after transformation.
However, it did not convert the origin to the world coordinate.
This is problematic when the user wants to determine
the paint's position and size with the origin being the canvas.
Specifically, this matters that when the paint is belonged
to a certain scene.
Now, the bounds() method returns the coordinates
of the paint's bounding box with the corrected world space.
User can figure out the actual boundary within the painted result.
Remark that, this may break the functional behavior compatibility.
This utility method allows access to a specific paint instance
by its unique identifier.
Experimental API:
- const Paint* Picture::paint(uint32_t id)
- const Tvg_Paint* tvg_picture_get_paint(Tvg_Paint* paint, uint32_t id)
This function computes a unique identifier value based on the provided string.
You can use this to assign a unique ID to the Paint object.
Experimental APIs:
- uint32_t Accessorr::id(const char* name)
- uint32_t tvg_accessor_id(const char* name)
